Stone Mountain make a string just as good if not better than WC.
I have one on my Patriot DC and have roughly 15k shots through it and so far no serving problems no fuzzing of the string.
After the shoot in period I had to put 1/2 a twist in the string and have not touched it since.
The peep rotates into position perfectly every time.

I do know what will be going back on my Patriot when this one needs replacing
